Following is an example of a C program that shows how to write data into the ATL buffer
RAM. The total number of data bytes to be transferred is 80 (decimal) that will be set into
the HcTransferCounter register as 50H. The data consists of four types of PTD data:
In all PTDs, we have assigned device address as 5 and endpoint 1. ActualBytes is always
zero (0). TotalBytes equals the number of payload data bytes transferred. However, note
that for bulk and control transfers, TotalBytes can be greater than MaxPacketSize.

However, if communication with a peripheral USB device is desired, the device should be
connected to the downstream port and pass enumeration.
